3.4.2 EPV – 3-wire version (Fig. 5)
The resistive transmitter with the converter is in the plant adjusted to have the output current signal
metered on the terminals 81-82 as follows:
•
in the position „open“ ..................................... 20 mA or 5 mA
•
in the position „closed“ ................................... 0 mA or4 mA
according to the specified version of the converter.
If the transmitter requires a new adjustment follow these steps:
•
Put the actuator to the position „closed“ and switch the power supply off.
•
Adjust the resistive transmitter according to the previous chapter. The resistance is to be metered
on the terminals X-Y (Fig. 5). The used transmitter resistance is 2000
Ω
or 100
Ω
.
•
Switch the converter
′
s power supply on.
•
Turn the adjusting trimmer ZERO (Fig. 5) to
adjust the output current signal rate measured
on the terminals 81-82 to 0 mA or 4mA.
•
Set the actuator to the position ”open“.
•
Turn the adjusting trimmer GAIN (Fig. 5) to
adjust the output current signal rate measured
on the terminals 81-82 to 20mA or 5 mA.
•
Check the output signal of the converter in the
both limit positions, and repeat the procedure if
needed.
Note:
The output signal of (0-20mA, 4-20mA or 0-5mA - according to the specification) can be adjusted at
the range from 85 up to 100% of the rated stroke stated on the actuator
′
s nameplate. At values less
than 85% the value of the output signal is reduced proportionally.
3.5 Adjustment of Capacitive Transmitter CPT1/A
The chapter describes adjustment of the capacitive transmitter to the specified parameters
(standard values of output signals) in case they are reset. The capacitive transmitter serves as a
position transmitter of electric actuators with unified output signal of 4÷20 mA in electric actuators
SP 0.1 , or as a feedback of a position controller, or if required it functions also as a remote position
transmitter of electric actuators with unified output signal of 4÷20 mA in electric actuators SP 0.1 with
controllers.
Note:
In case that reversed output signals are needed (in the position ”OPEN” minimum output signal)
contact personnel of service centres.
The capacitive transmitter CPT1/A is adjusted by the producer to the fixed operation stroke
according to the order and wired according to the wiring diagrams placed into the cover. Check the
power supply of the user after connecting to terminal of the terminal board before the transmitter is
electrically checked. Adjustment of the capacitive transmitter can be performed when the position
switches are adjusted. The adjustment is performed with the power supply of 230 V/50 Hz and
ambient temperature of 20
±
5
°
C.
The following versions of electric actuators with built capacitive transmitters can be specified :
A) The version without any power supply (2-wire version) for EA SP 0.1
B) The version with a power supply (2-wire version) for EA SP 0.1
C) The version CPT as a feedback to the position controller for EA SP 0.1 with controllers
A.) Adjustment of the Capacitive Transmitter without any Power Supply
Before connecting check the power supply. The measured voltage should be in range from 18
up to 28 V DC.
The voltage of the power supply must not be in any case higher than 30 V DC. The transmitter can be
irreversibly damaged!
